Would the data from this satellite be freely available to the public? I couldn't see anything obvious

As far as I can tell, they say: "Mission control and data distribution are managed by EUMETSAT." They have published their own blog post here: https://www.eumetsat.int/features/see-earths-atmosphere-neve...

There they say that: "Observations made by MTG-S1 will feed into data products that support national weather services …". So I guess there will be no simple, publicly available REST API or so... but if anybody finds anything, let us know here :)

Does anyone know what are we talking about in practice in terms of weather forecast prediction improvement? Like MAE/RMSE

This is an improvement as it provides better data and has nothing to do with the models that are used in a separate step to forcast anything. But that is said in the article as well, with the satellite being the first hyperspectral view on Europe and North Africa. I am not sure what to make if your question.

> I am not sure what to make if your question.

They are asking for a quantification of improvement. "better" predictions could range from "only experts notice" to "the daily/7 day weather is now noticeably more accurate for all citizens of Europe".

I recently met a European space startup founder and was surprised to learn how much space innovation is happening in Europe with ESA. Europe wants to become less depended on SpaceX and NASA, and is heavily investing there. More funding + strong aerospace programs at universities like TU Munich has led to companies like ISAR Aerospace (SpaceX competitor), which is great to see.

The Trump administration is probably helping quite a bit on two fronts here:

- A very strong political will to decouple strategic industries from the US

- The US is making it a lot harder to work there. So top talent stays in Europe.

nice find. so you need a client_id to access the API

If you are ever in Munich and want to find out more, be sure to visit the ESO Supernova[0]. [0] https://supernova.eso.org/

definitely worth a visit. loved the exhibition about the Atacama desert telescopes. especially great for kids.

This data is from the third generation of Meteosats, which are the European meteorological satellites. A lot like GOES in the north-America. The main improvement is really significant improvement in resolution. The resolution is, depending on the channel, 9 times better than in the second generation. The main improvement in forecasting comes due to better information in the initial condition of the numerical weather…

I use windy.com for its 'compare models', the models can differ by ~2C sometimes

As most EU projects yes. There was test data released last year to get you started. https://user.eumetsat.int/resources/user-guides/getting-star...

Well, at least in my experience with EU projects, they tend to be much more restrictive with data sharing than equivalent US institutions: e.g. a lot of paid EUMET data has publicly available NOAA equivalents - though usually of worse quality.
